Abstract
PURPOSE The purposes of this review article were to provide an introduction to and "bird's-eye" overview of the current evidence base for treatment of childhood apraxia of speech (CAS), identify some gaps and trends in this rapidly growing literature, and formulate some future research directions, in order to advance the evidence base and clinical practice for children with CAS. METHOD Following a brief introduction outlining important concepts, a narrative review of the CAS treatment literature is provided, and trends and future directions are identified based on this review. The review is organized around four fundamental treatment research questions: (a) "Does Treatment X work?", (b) "Does Treatment X work better than Treatment Y?", (c) "For whom does Treatment X work?", and (d) "What does 'work' mean, anyway?" RESULTS A wide range of CAS treatments with varying degrees of evidence for efficacy exists. Research is beginning to emerge that compares different treatments and seeks to determine optimal treatment parameters. Few studies to date have explored child-level predictors of treatment response, and the evidence base currently is limited in scope with respect to populations and outcomes studied. CONCLUSIONS A growing evidence base supports the efficacy of a number of treatments for CAS. However, many important gaps in the literature were identified that warrant redoubled and sustained research attention. Research is beginning to emerge that addresses treatment optimization, comparison, candidacy, and outcomes. Suggestions for future research are offered, and the concept of a hypothesized pathway was applied to CAS to illustrate how components of an intervention can effect change in a clinical goal and can help guide development and refinement of treatments for children with CAS.

Abstract
OBJECTIVE This study aimed to develop a Digital Speech Assessment Instrument to evaluate the phonological and motor speech skills of Brazilian Portuguese-speaking children and adolescents through six tasks: (a) word naming, (b) word imitation, (c) pseudoword imitation, (d) word repetition, (e) pseudoword repetition, and (f) diadochokinesis. METHOD The assessment instrument was developed and validated in a seven-step process, beginning with stimulus selection and ending with Pilot Study 1 (involving children and adolescents with typical speech development) and Pilot Study 2 (involving children and adolescents with speech sound disorders [SSDs]). Participants of the study included expert and nonexpert judges, children, and adolescents. RESULTS The Digital Speech Assessment Instrument contains 91 real words (61 in the naming task, 51 in the imitation task, and five in the repetition task), 26 pseudowords (26 in the imitation task and four in the repetition task), and six stimuli for diadochokinesis. The test contains stimuli in the form of images as well as audio and video recordings and allows for the analysis and storage of participant data in a virtual database. CONCLUSIONS This study described the development of the Digital Speech Assessment Instrument, available in Brazilian Portuguese for the evaluation of several aspects of speech production (including word and pseudoword naming, imitation, and repetition and diadochokinesis). The test was developed for children aged 2;0 (years;months) to 17;11 and is administered fully online. In the future, the instrument can be used to provide a timely and accurate diagnosis of SSDs.

Abstract
OBJECTIVE Speech sound disorder (SSD) describes a 'persistent difficulty with speech sound production that interferes with speech intelligibility or prevents verbal communication'. There is a need to establish which care pathways are most effective and efficient for children with SSD. Comparison of care pathways requires clearly defined, evidence-based, interventions and agreement on how to measure the outcomes. At present, no definitive list of assessments, interventions or outcomes exists. The objective of this umbrella review paper is to provide a rigorous and detailed list of assessments, interventions and outcomes which target SSD in children. DESIGN In December 2022, a systematic search of Ovid Medline, OVID Embase, CINAHL, PsycInfo and Cochrane and a number of grey literature platforms were undertaken. 18 reviews were included, and subsequently 415 primary research articles were assessed for data related to assessments, interventions or outcomes. The AMSTAR (Assessing the Methodological Quality of Systematic Reviews) framework was used to assess the quality of the retained reviews. SETTING Reviews were retained which took place in any setting. PARTICIPANTS The population is children of any age with a diagnosis of SSD of unknown origin. PRIMARY AND SECONDARY OUTCOME MEASURES Reviews reporting outcomes, assessment and interventions for children with SSD. RESULTS Extraction and analysis identified 37 assessments, 46 interventions and 30 outcome measures used in research reporting of SSD. Not all of the listed outcomes were linked to specific outcome measurement tools, but these were measurable through the use of one or more of the assessments extracted from the retained reviews. CONCLUSIONS The findings of this review will be used to develop a Core Outcome Set for children with SSD. The findings are part of a rigorous process essential for advancing healthcare research and practice in the specific area of speech and language therapy for children with SSD.

Southby L. Considering the role of speech processing in cleft-related speech sound disorders: Implications for causal pathways and classification systems. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2024. [PMID: 38206308 DOI: 10.1111/1460-6984.12993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Accepted: 11/13/2023] [Indexed: 01/12/2024]
Abstract
BACKGROUND Classification systems in healthcare support shared understanding of conditions for clinical communication, service monitoring and development, and research. Children born with cleft palate with or without cleft lip (CP+/-L) are at high risk of developing cleft-related speech sound disorder (SSD). The way cleft-related SSD is represented and described in SSD classification systems varies. Reflecting on the potential causal pathways for different cleft-related speech features, including the role of speech processing skills, may inform how cleft-related SSD is represented in classification systems. AIM & APPROACH To explore and reflect on how cleft-related SSD is represented in current SSD classification systems in the context of considering how speech processing skills and other factors may be involved in causal pathways of cleft speech characteristics (CSCs). MAIN CONTRIBUTION Variation in the representation of cleft-related SSD in classification systems is described. Potential causal pathways for passive cleft- related speech features and different active CSCs are explored. The factors involved in the development and/or persistence of different active CSCs may vary. Some factors may be specific to children born with CP+/-L, but if speech processing skills are also involved, this is an overlap with other SSD subtypes. Current evidence regarding relationships between different speech processing skills and active CSCs is limited. Implications for the representation of cleft-related SSD in SSD classification systems are discussed. CONCLUSION There are different categories of cleft-related speech features which are essential to understand and identify in children with cleft-related SSD to ensure appropriate management. Representation of these feature categories in classification systems could support understanding of speech in this population. Speech processing skills could be involved in the development and/or persistence of different active CSCs in individual children. Reflection and discussion on how cleft-related SSD is represented in classification systems in relation to other SSD subtypes may inform future iterations of these systems. Further work is needed to understand factors influencing the development and/or persistence of active CSCs, including speech processing skills. WHAT THIS PAPER ADDS What is already known on the subject Cleft-related speech sound disorder (SSD) is commonly described as being of known origin. The features of cleft-related SSD have been described extensively and several authors have also examined factors which may contribute to speech development and outcomes in children born with cleft palate +/- lip. There is limited evidence regarding the role of speech processing in the development and persistence of cleft-related SSD. What this study adds This paper reflects on how cleft-related SSD is represented in SSD classification systems in relation to key feature categories of cleft-related SSD and possible causal pathways for passive features and active cleft speech characteristics (CSCs). The role of cognitive speech processing skills is specifically considered alongside other factors that may contribute to the development of active CSCs. What are the clinical implications of this work? Causal pathways for different features of cleft-related SSD may vary, particularly between passive and active features, abut also between different active CSCs. Speech and language therapists (SLTs) need to differentially diagnose passive speech features and active CSCs. Consideration of the role of different speech processing skills and interactions with other potentially influencing factors in relation to active CSCs may inform clinical hypotheses and speech and language therapy (SLT) intervention. Representing key features of cleft-related SSD in classification systems may support understanding of cleft-related SSD in relation to other SSD subtypes.

Abstract
PURPOSE Music-based interventions are used in the treatment of childhood speech sound disorders (SSDs). Hypotheses on working mechanisms are being developed, focussing on shared neural processes. However, evidence of the effect of treatment with musical elements in SSDs in children is lacking. This study reviews the literature regarding the use of music-based interventions in the treatment of childhood SSDs. METHOD A systematic search in six databases was conducted, yielding 199 articles, eight of which met the inclusion criteria. Included articles were reviewed on study characteristics, patient characteristics, interventions, outcomes and methodological quality. RESULT This review included four case studies, three single-subject design studies and one cohort study. Seven studies reported positive outcomes on speech production, but outcome measures in the four studies with experimental design were not all aimed at the level of speech (motor) processes. Methodological quality was sufficient in one study. CONCLUSION Seven out of eight studies in this review report positive outcomes of music-based interventions in the treatment of SSDs. However, these outcomes are not sufficiently supported by evidence due to insufficient methodological quality. Suggestions for improving methodological quality in future research are presented.

Abstract
BACKGROUND 'Speech sound disorder' is an umbrella term that encompasses dysarthria, articulation disorders, childhood apraxia of speech and phonological disorders. However, differential diagnosis between these disorders is a persistent challenge in speech pathology, as many diagnostic procedures use symptom clusters instead of identifying an origin of breakdown in the speech and language system. AIMS This article reviews typical and disordered speech through the lens of two well-developed models of production-one focused on phonological encoding and one focused on speech motor planning. We illustrate potential breakdown locations within these models that may relate to childhood apraxia of speech and phonological disorders. MAIN CONTRIBUTION This paper presents an overview of an approach to conceptualisation of speech sound disorders that is grounded in current models of speech production and emphasises consideration of underlying processes. The paper also sketches a research agenda for the development of valid, reliable and clinically feasible assessment protocols for children with speech sound disorders. CONCLUSION The process-oriented approach outlined here is in the early stages of development but holds promise for developing a more detailed and comprehensive understanding of, and assessment protocols for speech sound disorders that go beyond broad diagnostic labels based on error analysis. Directions for future research are discussed. WHAT THIS PAPER ADDS What is already known on the subject Speech sound disorders (SSD) are heterogeneous, and there is agreement that some children have a phonological impairment (phonological disorders, PD) whereas others have an impairment of speech motor planning (childhood apraxia of speech, CAS). There is also recognition that speech production involves multiple processes, and several approaches to the assessment and diagnosis of SSD have been proposed. What this paper adds to existing knowledge This paper provides a more detailed conceptualisation of potential impairments in children with SSD that is grounded in current models of speech production and encourages greater consideration of underlying processes. The paper illustrates this approach and provides guidance for further development. One consequence of this perspective is the notion that broad diagnostic category labels (PD, CAS) may each comprise different subtypes or profiles depending on the processes that are affected. What are the potential or actual clinical implications of this work? Although the approach is in the early stages of development and no comprehensive validated set of tasks and measures is available to assess all processes, clinicians may find the conceptualisation of different underlying processes and the notion of potential subtypes within PD and CAS informative when evaluating SSD. In addition, this perspective discourages either/or thinking (PD or CAS) and instead encourages consideration of the possibility that children may have different combinations of impairments at different processing stages.

Spelling Proficiency of Children with a Resolved Phonological Speech Sound Disorder Treated with an Integrated Approach-A Long-Term Follow-Up Randomized Controlled Trial. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1154.

Abstract
Phonological developmental speech sound disorders (pDSSD) in childhood are often associated with later difficulties in literacy acquisition. The present study is a follow-up of the randomized controlled trial (RCT) on the effectiveness of PhonoSens, a treatment for pDSSD that focuses on improving auditory self-monitoring skills and categorial perception of phoneme contrasts, which could have a positive impact on later spelling development. Our study examines the spelling abilities of 26 German-speaking children (15 girls, 11 boys; mean age 10.1 years, range 9.3-11.2 years) 3-6 years after their successful completion of the PhonoSens treatment. Spelling assessment revealed that only 3 out of 26 participants developed a spelling disorder. In the overall population of fourth-graders, one in five children showed a spelling deficit; in another study of elementary school children, with resolved pDSSD, 18 of 32 children had a spelling deficit. Thus, the applied pDSSD treatment method appears to be associated with positive spelling development. Multiple regression analysis revealed that among the potentially predictive factors for German-speaking children with resolved pDSSD to develop later spelling difficulties, parental educational level and family risk for developmental language disorder (DLD) had an impact on children's spelling abilities; gender and the child's phonological memory had not.

Abstract
BACKGROUND Speech and language are interconnected systems, and language disorder often co-occurs with childhood apraxia of speech (CAS) and non-CAS speech sound disorders (SSDs). Potential trade-off effects between speech and language in connected speech in children without overt language disorder have been less explored. METHOD Story retell narratives from 24 children (aged 5;0-6;11 [years;months]) with CAS, non-CAS SSD, and typical development were analyzed in Systematic Analysis of Language Transcripts (SALT) regarding morphosyntactic complexity (mean length of C-unit in words [MLCU]), lexical diversity (moving-average type-token ratio [MATTR]), and linguistic accuracy (any linguistic error/bound morpheme omissions) and compared to 128 age-matched children from the SALT database. Linear and mixed-effects logistic regressions were performed with speech accuracy (percent phonemes correct [PPC]) and diagnostic group as predictors of the narrative variables. RESULTS PPC predicted all narrative variables. Poorer PPC was associated with lower MLCU and MATTR as well as a higher likelihood of linguistic errors. Group differences were only observed for the error variables. Comparison to the SALT database indicated that 13 of 16 children with CAS and SSD showed a higher-than-expected proportion of linguistic errors, with a small proportion explained by individual speech errors only. CONCLUSIONS The high occurrence of linguistic errors, combined with the relationship between PPC and linguistic errors in children with CAS/SSD, suggests a trade-off between speech accuracy and language output. Longitudinal studies are needed to investigate whether children with SSDs without language disorder show more language difficulties over time as linguistic demands increase.

Abstract
Late talkers are a heterogeneous group of children who experience delayed language development in the absence of other known causes. Late talkers show delays in expressive phonological development, but less is known about their receptive phonological development. In the current study, U.S. monolingual English-speaking typical talkers (TTs) (n = 23, mean age = 26.27 months, 57% male; 78.3% White) and late talkers (n = 22, mean age = 24.57 months, 59% male, 72.7% White) completed a Looking-While-Listening task to assess their sensitivity to mispronunciations. Results revealed that late talkers and TTs looked to the referent of a word for a shorter duration when it was mispronounced than when it was correctly pronounced, suggesting they were sensitive to mispronunciations. However, there were no significant differences between the two groups in their sensitivity to mispronunciations.

Abstract
PURPOSE This study examined the extent to which prelingual cochlear implant (CI) users show a slowed speaking rate compared with typical-hearing (TH) talkers when repeating various speech stimuli and whether the slowed speech of CI users relates to their immediate verbal memory. METHOD Participants included 10 prelingually deaf teenagers who received CIs before the age of 5 years and 10 age-matched TH teenagers. Participants repeated nonword syllable strings, word strings, and center-embedded sentences, with conditions balanced for syllable length and metrical structure. Participants' digit span forward and backward scores were collected to measure immediate verbal memory. Speaking rate data were analyzed using a mixed-design, repeated-measures analysis of variance, and the relationships between speaking rate and digit spans were evaluated by Pearson correlation. RESULTS Participants with CIs spoke more slowly than their TH peers during the sentence repetition task but not in the nonword string and word string repetition tasks. For the CI group, significant correlations emerged between speaking rate and digit span scores (both forward and backward) for the sentence repetition task but not for the nonword string or word string repetition task. For the TH group, no significant correlations were found. CONCLUSIONS The findings indicate a relation between slowed speech production, reduced immediate verbal memory, and diminished language capabilities of prelingual CI users, particularly for syntactic processing. These results support theories claiming that immediate memory, including components of a central executive, influences the speaking rate of these talkers. Implications for therapies designed to increase speech fluency in CI recipients are discussed. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.21644795.

Abstract
The differentiation between subtypes of speech sound disorder (SSD) and the involvement of possible underlying deficits is part of ongoing research and debate. The present study adopted a data-driven approach and aimed to identify and describe deficits and subgroups within a sample of 150 four to seven-year-old Dutch children with SSD. Data collection comprised a broad test battery including the Computer Articulation Instrument (CAI). Its tasks Picture Naming (PN), NonWord Imitation (NWI), Word and NonWord Repetition (WR; NWR) and Maximum Repetition Rate (MRR) each render a variety of parameters (e.g., percentage of consonants correct) that together provide a profile of strengths and weaknesses of different processes involved in speech production. Principal Component Analysis on the CAI parameters revealed three speech domains: (1) all PN parameters plus three parameters of NWI; (2) the remaining parameters of NWI plus WR and NWR; (3) MRR. A subsequent cluster analysis revealed three subgroups, which differed significantly on intelligibility, receptive vocabulary, and auditory discrimination but not on age, gender and SLPs diagnosis. The clusters could be typified as three specific profiles: (1) phonological deficit; (2) phonological deficit with motoric deficit; (3) severe phonological and motoric deficit. These results indicate that there are different profiles of SSD, which cover a spectrum of degrees of involvement of different underlying problems.

Abstract
PURPOSE Coarticulatory effects in speech vary across development, but the sources of this variation remain unclear. This study investigated whether developmental differences in intrasyllabic coarticulation degree could be explained by differences in children's articulatory patterns compared to adults. METHOD To address this question, we first compared the tongue configurations of 3- to 7-year-old German children to those of adults. The observed developmental differences were then examined through simulations with Task Dynamics Application, a Task Dynamics simulation system, to establish which articulatory modifications could best reproduce the empirical results. To generate syllables simulating the lack of tongue gesture differentiation, we tested three simulation scenarios. RESULTS We found that younger speakers use less differentiated articulatory patterns to achieve alveolar constrictions than adults. The simulations corresponding to undifferentiated control of tongue tip and tongue body resulted in (a) tongue shapes similar to those observed in natural speech and (b) higher degrees of intrasyllabic coarticulation in children when compared to adults. CONCLUSIONS Results provide evidence that differences in articulatory patterns contribute to developmental differences in coarticulation degree. This study further shows that empirically informed modeling can advance our understanding of changes in coarticulatory patterns across age.

Abstract
Deficits in temporal auditory processing, and in particular higher gap detection thresholds have been reported in children with inconsistent phonological disorder (IPD). Here we hypothesized that providing these children with extra time for phoneme identification may in turn enhance their phonological planning abilities for production, and accordingly improve not only consistency but also accuracy of their speech. We designed and tested a new temporal-based therapy, inspired by Core Vocabulary Therapy and called it T-CVT, where we digitally lengthened formant transitions between phonemes of words used for therapy. This allowed to target both temporal auditory processing and word phonological planning. Four preschool Persian native children with IPD received T-CVT for eight weeks. We measured changes in speech consistency (% inconsistency) and accuracy (percentage of consonants correct PCC) to assess the effects of the intervention. Therapy significantly improved both consistency and accuracy of word production in the four children: % inconsistency decreased from 59% on average before therapy to 2% post-T-CVT, and PCC increased from 61% to 92% on average. Consistency and accuracy were furthermore maintained or even still improved at three-month follow-up (2% inconsistency and 99% PCC). Results in a nonword repetition task showed the generalization of these effects to non-treated material: % inconsistency for nonwords decreased from 67% to 10% post-therapy, and PCC increased from 63% to 90%. These preliminary findings support the efficacy of the T-CVT intervention for children with IPD who show temporal auditory processing deficits as reflected by higher gap detection thresholds.

Abstract
OBJECTIVE The aim: To investigate the effectiveness of comprehensive approach in correctional work with older preschool children with speech disorders. PATIENTS AND METHODS Materials and methods: The research was conducted in 2018-2022. The research involved 250 children aged 5-7 years, who were divided into two groups. The experimental group consisted of 150 children with motor alalia (57 girls and 93 boys). The control group consisted of 100 children without speech disorders (48 girls and 52 boys). RESULTS Results: The analysis of outpatient cards of children with speech disorders of various aetiology was carried out. The main results of a comprehensive medical as well as psychological and pedagogical examination of children with motor alalia are highlighted. The result of the research revealed that organic lesion of the brain affects not only the clinical presentation of nonverbal symptoms, but also psychospeech development, in particular. CONCLUSION Conclusions: The expediency of using a comprehensive diagnostic methodology was proved, where the medical component consisted in studying the peculiarities of bioelectrical activity of the brain on electroencephalography, which reflects the process of its morphological maturation in ontogenesis.

Abstract
Background: The treatment of functional speech sound disorders (SSDs) in children is often lengthy, ill-defined, and without satisfactory evidence of success; effectiveness studies on SSDs are rare. This randomized controlled trial evaluates the effectiveness of the integrated SSD treatment program PhonoSens, which focuses on integrating phonological and phonetic processing according to the Integrated Psycholinguistic Model of Speech Processing (IPMSP). Methods: Thirty-two German-speaking children aged from 3.5 to 5.5 years (median 4.6) with functional SSD were randomly assigned to a treatment or a wait-list control group with 16 children each. All children in the treatment group and, after an average waiting period of 6 months, 12 children in the control group underwent PhonoSens treatment. Results: The treatment group showed more percent correct consonants (PCC) and a greater reduction in phonological processes after 15 therapy sessions than the wait-list control group, both with large effect sizes (Cohen’s d = 0.89 and 1.04). All 28 children treated achieved normal phonological abilities: 21 before entering school and 7 during first grade. The average number of treatment sessions was 28; the average treatment duration was 11.5 months. Conclusion: IPMSP-aligned therapy is effective in the treatment of SSD and is well adaptable for languages other than German.

Abstract
Purpose: The current study aims to provide normative data for the maximum repetition rate (MRR) development of Dutch-speaking children based on a large cross-sectional study using a standardised protocol.Method: A group of 1014 typically developing children aged 3;0 to 6;11 years performed the MRR task of the Computer Articulation Instrument (CAI). The number of syllables per second was calculated for mono-, bi-, and trisyllabic sequences (MRR-pa, MRR-ta, MRR-ka, MRR-pata, MRR-taka, MRR-pataka). A two-way mixed ANOVA was conducted to compare the effects of age and gender on MRR scores in different MRR sequences.Result: The data analysis showed that overall MRR scores were affected by age group, gender and MRR sequence. For all MRR sequences the MRR increased significantly with age. MRR-pa was the fastest sequence, followed by respectively MRR-ta, MRR-pata, MRR-taka, MRR-ka and MRR-pataka. Overall MRR scores were higher for boys than for girls, for all MRR sequences.Conclusion: This study presents normative data of MRR of Dutch-speaking children aged 3;0 to 6;11 years. These norms might be useful in clinical practice to differentiate children with speech sound disorders from typically developing children. More research on this topic is necessary. It is also suggested to collect normative data for other individual languages, using the same protocol.

Abstract
The purpose of this study was to investigate relationships between speech inconsistency, speech production skills, phonological awareness and nonword repetition (NWR) in 24 preschool-aged Finnish-speaking children with speech sound disorder (SSD) and in 31 children with typical speech and language development (TD). Speech inconsistency was assessed by a picture-naming task repeated three times during one assessment session. The participants' speech production skills were assessed with the Finnish Test for Phonology and a diadochokinetic (DDK) task. Phonological awareness was investigated by the tasks of Rhyme and initial syllable awareness and Syllable segmentation, and NWR by ten 2-4-syllabic nonwords. The findings indicated that the children with SSD were less accurate in speech production and NWR than the children with TD. No difference was found in phonological awareness. Among the children with SSD, speech inconsistency was correlated with accuracy in overall speech production, DDK task, and NWR. Among the children with TD, speech inconsistency was correlated with accuracy in overall speech production, partly with phonological awareness, and with NWR. The results provide support for the idea that when assessing speech inconsistency in children with SSD, a process-oriented approach may be needed in order to obtain an adequately broad picture of their skill profiles.

Abstract
SATB2‐associated syndrome (SAS) is a neurodevelopmental disorder caused by heterozygous pathogenic variants in the SATB2 gene, and is typically characterized by intellectual disability and severely impaired communication skills. The goal of this study was to contribute to the understanding of speech and language impairments in SAS, in the context of general developmental skills and cognitive and adaptive functioning. We performed detailed oral motor, speech and language profiling in combination with neuropsychological assessments in 23 individuals with a molecularly confirmed SAS diagnosis: 11 primarily verbal individuals and 12 primarily nonverbal individuals, independent of their ages. All individuals had severe receptive language delays. For all verbal individuals, we were able to define underlying speech conditions. While childhood apraxia of speech was most prevalent, oral motor problems appeared frequent as well and were more present in the nonverbal group than in the verbal group. For seven individuals, age‐appropriate Wechsler indices could be derived, showing that the level of intellectual functioning of these individuals varied from moderate–mild ID to mild ID‐borderline intellectual functioning. Assessments of adaptive functioning with the Vineland Screener showed relatively high scores on the domain “daily functioning” and relatively low scores on the domain “communication” in most individuals. Altogether, this study provides a detailed delineation of oral motor, speech and language skills and neuropsychological functioning in individuals with SAS, and can provide families and caregivers with information to guide diagnosis, management and treatment approaches.

Abstract
OBJECTIVE Children with speech sound disorders (SSDs) have difficulties affecting different levels of speech production. For treatment to be beneficial, it is important to differentiate between Childhood Apraxia of Speech (CAS) - a motor speech disorder with deficits in speech praxis - and other SSDs (nonCAS-SSD). We have previously developed a motor speech examination Dynamisk motorisk talbedömning (DYMTA). We aimed to evaluate DYMTAs reliability and validity in a small-scale sample to estimate DYMTAs usability in diagnostic settings. METHODS Speech, language, and oral motor abilities were assessed in 45 children between 40 and 106 months. Intra- and inter-rater reliability of DYMTA were analyzed. Further, DYMTAs ability to validly discriminate between children with CAS and nonCAS-SSD was assessed. RESULTS The intra-rater reliability for the scores of DYMTA was strong, with ICCs ranging from 0.97 to 1.0. DYMTA total score had strong inter-rater reliability as evidenced both by the agreement estimates (DYMTA-A: 0.91 and DYMTA-B: 0.87) and the ICCs (0.97 and 0.96). Inter-rater reliability was also strong for the separate subscores on agreement estimates and for all subscores on ICCs, except for the Prosody subscores. DYMTA accurately discriminated between children with CAS and nonCAS-SSD in this small sample with an AUC of 0.92 for DYMTA-A and 0.94 for DYMTA-B. CONCLUSIONS With its focus on speech movements, DYMTA could serve as a valuable addition to other tests when assessing children's speech motor performance. This first examination suggests that DYMTA may be both a reliable and valid tool in the diagnostic process of SSD.

Abstract
Purpose To assess the concurrent validity of two tasks used to inform diagnosis of childhood apraxia of speech (CAS), this study evaluated the agreement between the Syllable Repetition Task (SRT) and the Maximum Repetition Rate of Trisyllables (MRR-Tri). Method A retrospective analysis was conducted with 80 children 7-16 years of age who were referred for treatment studies. All children had a speech sound disorder, and all completed both the SRT and the MRR-Tri. On each task, children were classified as meeting or not meeting the tool's threshold for CAS based on the sound sequencing errors demonstrated. Results The two tasks were in agreement for 47 participants (59% of the sample); both tasks classified 13 children as meeting the threshold for CAS and 34 children as not meeting the threshold for CAS. However, the two tasks disagreed on CAS classification for 33 children (41% of the sample). Overall, the MRR-Tri identified more children as having sound sequencing errors indicative of CAS (n = 39) than did the SRT (n = 20). Conclusions These two tasks of sound sequencing differ in the children they identify with CAS, possibly due to aspects of the underlying task requirements (e.g., time pressure). The SRT and the MRR-Tri should not be used in isolation to identify CAS but may be useful as part of a balanced CAS assessment battery that includes additional tasks that inform the nature of the impairment and that aid treatment planning.

Abstract
OBJECTIVE To analyze the utility of Ankara Articulation Test (AAT) for the diagnosis of Speech Sound Disorders (SSD) in children by an Otolaryngologist independent of Speech-Language Pathologist (SLP). METHODS In this prospective single-center study, 83 children comprising 45 boys (54.2%) and 38 girls (45.8%) were enrolled. AAT was applied to the children aged 3-12 years with primary SSD who presented to the otolaryngology outpatient service. Video recording was carried out while testing and the responses to the test were evaluated by another otolaryngologist and SLP. RESULTS A perfectly significant agreement was found between the speech-language pathologist and otolaryngologist's assessments (Cronbach's Alpha > 0.80). CONCLUSION Otolaryngologists could evaluate SSD with the help of AAT as well as an SLP analysis. Standardized visual tests, such as the AAT, assist the otolaryngologist in the diagnosis of SSD in outpatient clinics.

Abstract
In the absence of any neuropsychiatric condition, older adults may show declining performance in several cognitive processes and among them, in retrieving and producing words, reflected in slower responses and even reduced accuracy compared to younger adults. To overcome this difficulty, healthy older adults implement compensatory strategies, which are the focus of this paper. We provide a review of mainstream findings on deficient mechanisms and possible neurocognitive strategies used by older adults to overcome the deleterious effects of age on lexical production. Moreover, we present findings on genetic and lifestyle factors that might either be protective or risk factors of cognitive impairment in advanced age. We propose that "aging-modulating factors" (AMF) can be modified, offering prevention opportunities against aging effects. Based on our review and this proposition, we introduce an integrative neurocognitive model of mechanisms and compensatory strategies for lexical production in older adults (entitled Lexical Access and Retrieval in Aging, LARA). The main hypothesis defended in LARA is that cognitive aging evolves heterogeneously and involves complementary domain-general and domain-specific mechanisms, with substantial inter-individual variability, reflected at behavioral, cognitive, and brain levels. Furthermore, we argue that the ability to compensate for the effect of cognitive aging depends on the amount of reserve specific to each individual which is, in turn, modulated by the AMF. Our conclusion is that a variety of mechanisms and compensatory strategies coexist in the same individual to oppose the effect of age. The role of reserve is pivotal for a successful coping with age-related changes and future research should continue to explore the modulating role of AMF.

We agree with Cristina Romani (CR) about reducing confusion and agree that the issues raised in her commentary are central to the study of apraxia of speech (AOS). However, CR critiques our approach from the perspective of basic cognitive neuropsychology. This is confusing and misleading because, contrary to CR's claim, we did not attempt to inform models of typical speech production. Instead, we relied on such models to study the impairment in the clinical category of AOS (translational cognitive neuropsychology). Thus, the approach along with the underlying assumptions is different. This response aims to clarify these assumptions, broaden the discussion regarding the methodological approach, and address CR's concerns. We argue that our approach is well-suited to meet the goals of our recent studies and is commensurate with the current state of the science of AOS. Ultimately, a plurality of approaches is needed to understand a phenomenon as complex as AOS.

Abstract
This study investigated the underlying nature of apraxia of speech (AOS) by testing two competing hypotheses. The Reduced Buffer Capacity Hypothesis argues that people with AOS can plan speech only one syllable at a time Rogers and Storkel [1999. Planning speech one syllable at a time: The reduced buffer capacity hypothesis in apraxia of speech. Aphasiology, 13(9-11), 793-805. https://doi.org/10.1080/026870399401885]. The Program Retrieval Deficit Hypothesis states that selecting a motor programme is difficult in face of competition from other simultaneously activated programmes Mailend and Maas [2013. Speech motor programming in apraxia of speech: Evidence from a delayed picture-word interference task. American Journal of Speech-Language Pathology, 22(2), S380-S396. https://doi.org/10.1044/1058-0360(2013/12-0101)]. Speakers with AOS and aphasia, aphasia without AOS, and unimpaired controls were asked to prepare and hold a two-word utterance until a go-signal prompted a spoken response. Phonetic similarity between target words was manipulated. Speakers with AOS had longer reaction times in conditions with two similar words compared to two identical words. The Control and the Aphasia group did not show this effect. These results suggest that speakers with AOS need additional processing time to retrieve target words when multiple motor programmes are simultaneously activated.

Abstract
Purpose The aim of this study was to determine the discriminative features that might contribute to differentiation of childhood apraxia of speech (CAS) from other speech sound disorders (SSDs). Method A comprehensive literature search was conducted for articles or doctoral dissertations that included ≥ 1 child with CAS and ≥ 1 child with SSD. Of 2,071 publications screened, 53 met the criteria. Articles were assessed for (a) study design and risk of bias; (b) participant characteristics and confidence in diagnosis; and (c) discriminative perceptual, acoustic, or kinematic measures. A criterion was used to identify promising studies: American Academy of Neurology study design (Class III+), replicable participant descriptions and adequate confidence in diagnosis (≥ 3), and ≥ 1 discriminative and reliable measure. Results Over 75% of studies were retrospective, case-control designs and/or assessed English-speaking children. Many studies did not fully describe study design and quality. No studies met the Class I (highest) quality rating according to American Academy of Neurology guidelines. CAS was mostly compared to speech delay/phonological disorder. Only six studies had diagnostic confidence ratings of 1 (best). Twenty-six studies reported discriminative perceptual measures, 14 reported discriminative acoustic markers, and four reported discriminative kinematic markers. Measures were diverse, and only two studies directly replicated previous findings. Overall, seven studies met the quality criteria, and another eight nearly met the study criteria to warrant further investigation. Conclusions There are no studies of the highest diagnostic quality. There are 15 studies that can contribute to further diagnostic efforts discriminating CAS from other SSDs. Future research should utilize careful diagnostic design, support replication, and adhere to standard reporting guidelines. Supplemental Material https://doi.org/10.23641/asha.13158149.

Abstract
PURPOSE Childhood apraxia of speech (CAS) is difficult to diagnose because there is little agreement on objective clinical markers. Since studies of phonological development in French-speaking children are scarce, there are even fewer recognised markers in French as compared to English. This study aims to determine if a set of operationalised, quantitative measures derived from clinical markers of CAS in English corroborate with clinical CAS diagnosis in French-speaking children. This research contributes to improving differential diagnosis of CAS and phonological disorder cross-linguistically. METHOD We collected data from five children diagnosed with CAS, nine children diagnosed with phonological disorder, and 75 typically-developing children aged 5.10-9.2 years old. All children were assessed on three speech production tasks: picture-naming, non-word repetition, and diadochokinesis. We extracted 20 quantitative measures corresponding to commonly accepted clinical features of CAS. RESULT Similar to English-speaking children, French-speaking children with CAS exhibited a high number of vowel errors, consonant and cluster errors, consonant epentheses, devoicing errors, slow diadochokinesis rate, more inconsistency and increased errors with longer words. Contrary to studies on English, these children with CAS did not produce intrusive schwas or vowels. CONCLUSION This multiple-case study highlights the need for cross-linguistic diagnostic criteria for CAS.

Abstract
Purpose The purpose of this study was to determine the extent to which school-age children with speech sound disorder (SSD) exhibit concomitant reading difficulties and examine the extent to which phonological processing and speech production abilities are associated with increased likelihood of reading risks. Method Data were obtained from 120 kindergarten, first-grade, and second-grade children who were in receipt of school-based speech therapy services. Children were categorized as being "at risk" for reading difficulties if standardized scores on a word decoding measure were 1 SD or more from the mean. The selected predictors of reading risk included children's rapid automatized naming ability, phonological awareness (PA), and accuracy of speech sound production. Results Descriptive results indicated that just over 25% of children receiving school-based speech therapy for an SSD exhibited concomitant deficits in word decoding and that those exhibiting risk at the beginning of the school year were likely to continue to be at risk at the end of the school year. Results from a hierarchical logistic regression suggested that, after accounting for children's age, general language abilities, and socioeconomic status, both PA and speech sound production abilities were significantly associated with the likelihood of being classified as at risk. Conclusions School-age children with SSD are at increased risk for reading difficulties that are likely to persist throughout an academic year. The severity of phonological deficits, reflected by PA and speech output, may be important indicators of subsequent reading problems.

Abstract
BACKGROUND The speculation that apraxia of speech (AOS) is not a unitary diagnosis, but consists of different subtypes instead, has been around for decades. However, attempts to empirically substantiate such a notion remain few and far between. AIMS The primary objective of this article is to consider the different bases for identifying subtypes of AOS, review existing evidence regarding subtypes under each classification basis, and provide discussion and implications for future research. MAIN CONTRIBUTION AOS subtypes have been proposed on the basis of clinical symptomatology, theoretical constructs, and an analogy to limb apraxia. Different possible subtypes of AOS are reviewed, along with their empirical support and limitations. Empirical evidence, particularly in the context of a progressive disease, supports the idea that AOS diagnosis may capture different underlying impairments of speech motor planning. Future research to advance our understanding of AOS should carefully consider the basis for subtype classification, and include large sample sizes to differentiate individual variability from possible subtypes. CONCLUSIONS Several proposed AOS subtypes have found some support in the literature. Further research is needed to determine the validity, coherence and utility of possible AOS subtypes for theoretical and clinical purposes.

Abstract
Purpose This study aims to give an insight in clinical reasoning (diagnosis and intervention) of speech-language pathologists (SLPs) in the Netherlands for children with speech sound disorder (SSD). Method The study featured a mixed-method (qualitative and quantitative) design. Semistructured interviews containing nondirective, open-ended questions were conducted with 33 SLPs, which were analyzed using a constant comparative analysis. Other SLPs (137) filled out a questionnaire on the same topics. Multiple-choice questions were analyzed by descriptive frequencies, while open-ended questions were analyzed thematically. Results The results indicate that SLPs use a variety of assessments to diagnose SSD, complemented by observation and, often, case history. In total, 85 different diagnostic labels were reported. The choice of intervention is based on what is appealing to the child and what matches his or her age as well as on the specific diagnosis and severity. Interventions are used for multiple speech disorders, and according to SLPs, parents play a large role in diagnostics and intervention. Conclusion These results reveal the need for (a) a clear and consistent terminology of diagnoses in the field of pediatric SSD, (b) a fast and easy-to-administer comprehensive differential diagnostic instrument in combination with an instrument to assess participation in everyday life, and (c) a tool to conduct a case history online.

Abstract
Purpose: A recent behavioural experiment featuring a noise masking paradigm suggests that Apraxia of Speech (AOS) reflects a disruption of feedforward control, whereas feedback control is spared and plays a more prominent role in achieving and maintaining segmental contrasts. The present study set out to validate the interpretation of AOS as a possible feedforward impairment using computational neural modelling with the DIVA (Directions Into Velocities of Articulators) model.Method: In a series of computational simulations with the DIVA model featuring a noise-masking paradigm mimicking the behavioural experiment, we investigated the effect of a feedforward, feedback, feedforward + feedback, and an upper motor neuron dysarthria impairment on average vowel spacing and dispersion in the production of six/bVt/speech targets.Result: The simulation results indicate that the output of the model with the simulated feedforward deficit resembled the group findings for the human speakers with AOS best.Conclusion: These results provide support to the interpretation of the human observations, corroborating the notion that AOS can be conceptualised as a deficit in feedforward control.

Abstract
Speech Sound Disorders (SSDs) is a generic term used to describe a range of difficulties producing speech sounds in children (McLeod and Baker, 2017). The foundations of clinical assessment, classification and intervention for children with SSD have been heavily influenced by psycholinguistic theory and procedures, which largely posit a firm boundary between phonological processes and phonetics/articulation (Shriberg, 2010). Thus, in many current SSD classification systems the complex relationships between the etiology (distal), processing deficits (proximal) and the behavioral levels (speech symptoms) is under-specified (Terband et al., 2019a). It is critical to understand the complex interactions between these levels as they have implications for differential diagnosis and treatment planning (Terband et al., 2019a). There have been some theoretical attempts made towards understanding these interactions (e.g., McAllister Byun and Tessier, 2016) and characterizing speech patterns in children either solely as the product of speech motor performance limitations or purely as a consequence of phonological/grammatical competence has been challenged (Inkelas and Rose, 2007; McAllister Byun, 2012). In the present paper, we intend to reconcile the phonetic-phonology dichotomy and discuss the interconnectedness between these levels and the nature of SSDs using an alternative perspective based on the notion of an articulatory "gesture" within the broader concepts of the Articulatory Phonology model (AP; Browman and Goldstein, 1992). The articulatory "gesture" serves as a unit of phonological contrast and characterization of the resulting articulatory movements (Browman and Goldstein, 1992; van Lieshout and Goldstein, 2008). We present evidence supporting the notion of articulatory gestures at the level of speech production and as reflected in control processes in the brain and discuss how an articulatory "gesture"-based approach can account for articulatory behaviors in typical and disordered speech production (van Lieshout, 2004; Pouplier and van Lieshout, 2016). Specifically, we discuss how the AP model can provide an explanatory framework for understanding SSDs in children. Although other theories may be able to provide alternate explanations for some of the issues we will discuss, the AP framework in our view generates a unique scope that covers linguistic (phonology) and motor processes in a unified manner.

Abstract
BACKGROUND Systematic reviews of treatment trials for children with speech and language difficulties often exemplify the limited clinical usefulness of the evidence base, reflecting recent literature in evidence-based medicine. Other studies report that clinicians often fail to seek information about best practice, across the health professions. Consequently, clinical researchers, including those in speech-language pathology, have sought alternative methodologies for determining best practice. SUMMARY Some approaches focus on "pragmatic trials," usually as part of existing health services. Others place case management of individuals at the centre of intervention presenting studies of one or more cases, including N-of-1 randomized controlled trials and cross-over group designs. Clinical case studies can provide important theoretical data contributing to our understanding of the development of typical and atypical communication. Precision medicine (also known as personalized medicine) is an emerging approach to building the clinical evidence base that acknowledges the importance of individual genetic and environmental differences between people. With increasing knowledge of aetiological heterogeneity, even within children presenting with the same diagnosis (e.g., childhood apraxia of speech), data reinforce the edict that children are not all born equal. Key Message: This review argues that to understand response to treatment, it is critical to examine child-related factors as well as the variables of the intervention itself.

Abstract
Background With respect to the clinical criteria for diagnosing childhood apraxia of speech (commonly defined as a disorder of speech motor planning and/or programming), research has made important progress in recent years. Three segmental and suprasegmental speech characteristics-error inconsistency, lengthened and disrupted coarticulation, and inappropriate prosody-have gained wide acceptance in the literature for purposes of participant selection. However, little research has sought to empirically test the diagnostic validity of these features. One major obstacle to such empirical study is the fact that none of these features is stated in operationalized terms. Purpose This tutorial provides a structured overview of perceptual, acoustic, and articulatory measurement procedures that have been used or could be used to operationalize and assess these 3 core characteristics. Methodological details are reviewed for each procedure, along with a short overview of research results reported in the literature. Conclusion The 3 types of measurement procedures should be seen as complementary. Some characteristics are better suited to be described at the perceptual level (especially phonemic errors and prosody), others at the acoustic level (especially phonetic distortions, coarticulation, and prosody), and still others at the kinematic level (especially coarticulation, stability, and gestural coordination). The type of data collected determines, to a large extent, the interpretation that can be given regarding the underlying deficit. Comprehensive studies are needed that include more than 1 diagnostic feature and more than 1 type of measurement procedure.

Abstract
BACKGROUND/AIMS Maximum repetition rate (MRR) is often used in the assessment of speech motor performance in older children and adults. The present study aimed to evaluate a standardized protocol for MRR assessment in young children in Dutch. METHODS The sample included 1,524 children of 2-7 years old with no hearing difficulties and Dutch spoken in their nursery or primary school and was representative for children in the Netherlands. The MRR protocol featured mono-, tri-, and bisyllabic sequences and was computer-implemented to maximize standardization. RESULTS Less than 50% of the 2-year-olds could produce >1 monosyllabic sequence correctly. Children who could not correctly produce ≥2 monosyllabic sequences could not produce any of the multisyllabic sequences. The effect of instruction ("faster" and "as fast as possible") was small, and multiple attempts yielded a faster MRR in only 20% of the cases. MRRs did not show clinically relevant differences when calculated over different numbers of repeated syllables. CONCLUSIONS The MRR protocol is suitable for children of 3 years and older. If children cannot produce at least 2 of the monosyllabic sequences, the multisyllabic tasks should be omitted. Furthermore, all fast attempts of each sequence should be analyzed to determine the fastest MRR.
